    update identity role tests to work w/ pre-prov

    I don't see any limitations by using pre-provisioned
    credentials for these tests:

    * test_role_create_update_show_list
    * test_list_roles
    * test_implied_roles_create_check_show_delete
    * test_roles_hierarchy
    * test_assignments_for_implied_roles_create_delete
    * test_domain_roles_create_delete
    * test_implied_domain_roles
    * test_assignments_for_domain_roles
    * test_list_all_implied_roles
    * test_grant_list_revoke_role_to_user_on_project
    * test_grant_list_revoke_role_to_user_on_domain
    * test_grant_list_revoke_role_to_group_on_project
    * test_grant_list_revoke_role_to_group_on_domain

    By setting force_tenant_isolation=False these tests now be
    can executed with backends that don't allow user creation
    (immutable user source) like LDAP.
